Pipe welding automatic feeding device

Abstract

The invention provides a pipe welding automatic feeding device. Automatic pipe discharging is controlled by forming a pipe discharging channel, with a bottom opening, in the middle of a sliding frameand further arranging discharging air cylinders; furthermore, by arranging an air cylinder and vertical slide rails, the distance between the pipe discharging channel and a pipe conveying mechanism iscontrolled, accordingly, it is guaranteed that only one pipe drops at a time, meanwhile, the sliding frame is shaken when material blocking occurs, and material dropping is facilitated; by arranginga movable discharging mechanism, bundles of pipes can be loaded conveniently, the movable discharging mechanism adapts to incoming pipes with different lengths, furthermore, by arranging a pressing mechanism, the pipes can be pressed and put in order conveniently, and the discharging accuracy is guaranteed; an included angle which is greater than 0 degree and smaller than 90 degrees is formed between the pipe discharging channel and welding frame feeding guide rails, and the pipes can move inside a welding frame conveniently; and a positioning mechanism is arranged, the pipes are clamped within the welding frame and positioned, and subsequent automatic welding is facilitated.

Description

technical field

[0001] The invention relates to the field of welding equipment, in particular to an automatic feeding device for pipe welding. Background technique

[0002] At present, for the welding of pipes, because the size and shape of the welded parts are not regular enough, it is difficult to automatically align them, so manual welding is generally used. However, manual welding has the following problems: low work efficiency, high labor costs, and the gas generated during the welding process has toxic side effects on the human body; in addition, the consistency of the products produced by manual welding is poor, and the product quality is difficult to guarantee. Therefore, it is urgent to develop an automatic welding device, which can replace manual work and realize automatic welding.

[0003] For products with large consumption and relatively regular shape, such as guardrails, the size and shape of the welded parts are relatively regular, especially the vertical pip...
